The invention discloses an
energy storage power supply. The
energy storage power supply comprises a
battery cell, a shell and a sealing piece. The
battery cell comprises an
electrode and / or an anti-explosion valve, a containing cavity for containing the
battery cell is formed in the shell, the shell is provided with a mounting wall, a fixing structure for fixing the battery
cell is formed on the side, located in the containing cavity, of the mounting wall, a through hole is formed in the corresponding position of the fixing structure, and the
electrode and / or the anti-explosion valve of the battery
cell are / is communicated with the outside of the containing cavity through the through hole. The sealing element covers one side, far away from the accommodating cavity, of the mounting wall to isolate the battery
cell from the outside, a groove is formed in the periphery of one of the sealing element and the mounting wall, a bulge is formed on the periphery of the other one, and the bulge is inserted into the groove. Therefore, the battery cell is accommodated in the accommodating cavity of the shell, and the through hole is formed, so that the battery cell can be connected with external equipment. And the bulge of one of the sealing element and the mounting wall is inserted into the groove of the other one of the sealing element and the mounting wall, so that close fit between the sealing element and the shell is realized, and water or other external substances are effectively prevented from permeating into the shell through the seam.
